NONREFILLABLE BOTTLE Filed April so, 1937 M ve?? a?? Patented Aug. 30, 1938 UNITED .STATES PATENT vOFFifCE 3 Claims.

' 5 Valves whereby it shall be impossible to refill the bottle under any conditions.

It has been proposed to make a non-refillable bottle with a plurality of valves so that one valve shall supplement the other to make relling of the bottle extremely difficult or impossible. However, most of the proposed structures havefailed to accomplish this desired result under some conditions; for example when the bottle isheld in approximately horizontal position, all of the valves are in completely open or partly open position so that liquid might flow into the bottle through the valves and thereby ll the bottle.

Another object of my invention is to provide a non-rellable bottle .of this general character which shall includea plurality of valves but shall have the valves so constructed and related that at least one thereof shall always be closed except when the bottle is tilted-at an angle to .the horizontal with its mouth downward.

Another object of the-invention is to provide such a non-rellable bottle which shall include a plurality of hinged valves that have the axes of their hinges disposed parallel to each other and at opposite sides of an axial plane of the passage through the neck of the bottle which is parallel to the axes of the hinges so that at least one valve shall be closed when the bottle neck is disposed in any position at which liquid might flow into the bottle by action of gravity and so that at least one valve shall be closed upon any attempt to force liquid into the bottle under pressure.

A further object is to provide in such a nonrellable bottle novel and improved means for hingedly mounting and assembling the valves in a casing so that the device shall be simple and inexpensive in structure and assembly.

Other objects, advantages and results of the invention will appear from the following description when read in conjunction with the accompanying drawing.

Referring to the accompanying drawing,

Figure 1 is a vertical longitudinal sectional View through the neck of a non-rellable bottle embodying the invention, showing the bottle in upright or vertical position.

Figure 2 is a similar view showing the bottle neck in horizontal position.

Figure 3 is a like View showing the bottle neck tilted into aposition atan angle to the horizontal with the mouth of the bottledownward.

'Specically describing the illustrated embodiment of the invention, the reference character A designates a bottle neck in which is secured as by cementing or in any other-suitable manner, a valve device. B forpreventing relling of the bottle.

.As shown, this valve device includes three coaxially superposedand connected tubular sections I, 2 .and ..3 whose .exterior .diameters vare such as to fit snugly against the inner walls of the bottleneclnthe sections having .therespective. passages 4, l5 and '.6 vtherethrough communicating with the passages of theother sections. The innermostsectionl has an upstandingange 'Iwhich seatsin.a..corresponding rabbet 8in the next adjacent section 2. `'I'hislange hastransverse notches 8 opening through its edges and alined in chordal relation to the section I in which notches are rotatably seated trunnions I0 at opposite sides of a ap valve II which is arranged to seat upon an outwardly facing valve seat or shoulder I2.

The hinge trunnions I3 are disposed at one side of and parallel to an axial plane of the neck of the bottle, and a second ilap valve I3 is mounted between the sections 2 and 3. As shown, this second valve I3 has opposite hinge trunnions I4 seated in transverse notches I5 in an upstanding flange I6 at the outer end of the section 2, the axes of the hinge trunnions I4 being disposed parallel to the axis of the hinge trunnions I0 of the valve I I and at the opposite side of said axial plane of the bottle neck; and the valve seats upon a shoulder or valve seat I'I. The section 3 has a rabbet I8 in which the flange I6 is fitted so as to positively hold the hinge trunnions I4 against displacement from the casing of the valve device. 'Ihe two valves II and I3 are mounted so as to swing outwardly into open position away from their respective seats and toward the mouth of the bottle to open the passages 4, 5 and 6 and permit the contents of the bottle to flow through the bottle neck and valve device, and when the bottle is disposed with its mouth directed upwardly the valves II and I3 are caused to seat by gravitational action and prevent liquid from flowing through the neck of the bottle into the bottle.

Preferably a vent passage I9 is formed in the section l to admit air into the bottle as the liquid flows therefrom, and this vent is controlled by an auxiliary valve ap 20 carried by the valve i! so that the valve flap 20 opens and closes the passage i9 simultaneously with opening and closing of the valve il.

With the device so constructed and arranged, it will be seen that when the bottle is tilted With the passage through the neck at an angle to the horizontal and with the mouth directed downwardly, as shown in Figure 3, both of the valves il and i3 will open by gravitational action, but when the bottle is disposed with its neck horizontal and with the axes of the hinge trunnions disposed horizontally, at least one of the valves will be closed as shown in Figure 2. When the neck of the bottle is disposed horizontally With the axes of the valve trunnions disposed vertically, slight tilting of the mouth of the bottle upwardly or slight pressure as would be occasioned by liquid owing into the bottle will close at least one of the valves. Should it be attempted to ll the bottle under pressure, at least one of the valves will be closed by the pressure of the infiowing liquid. It will therefore be seen that it is practically impossible to rell a bottle embodying my valve device without destroying at least the outermost valve H.

To prevent tampering with the valves il and I3, a baille 2! is secured in the outer end oi the outer section 3, this baffle being shown as ccmprising a plurality of superposed parallel disks 22 spaced longitudinally of the device and carried by tie members 23. The liquid may ow outwardly between the rings 22 but it will be impossible to insert any implement into the valve device.

The valve device may be formed of any suitable material, for example, metal, glass, porcelain or Bakelite, and preferably will be constructed so that any attempt to pull the device from the bottle neck will result in breaking or destruction of the device.

Other modications and changes in the details of structure of the valve device will occur to those skilled in the art as Within the scope and spirit of the invention.

Having thus described my invention, what I claim is:

1. A valve device for insertion into the neck of a bottle including a casing formed of two superposed coaxial tubular sections, one having an upstanding ange with transverse notches opening through the edges of the flange and alined in chordal relation to said section and the other having a rabbet receiving said flange to connect said sections together and close the outer ends of said notches, a flap valve disposed transversely of said casing and having oppositely disposed alined hinge trunnions one of which is rotatably mounted in each of said notches whereby said sections positively hold said ap between them against displacement from the casing, and one of said sections having a seat for said valve, whereby the valve may swing against and away from said seat to close and open the passage through said casing.

2. A valve device for insertion into a bottle neck comprising a casing having a main passage and an adjacent vent passage therethrough, seats for each of said passages, and a valve hingedly mounted in said casing between said passages and having a main nap and an auxiliary flap for said passages, respectively, whereby said passages are opened and closed simultaneously.

3. The combination with a bottle having a neck, ci a valve device including a casing fitted in said neck and having a passage therethrough, and a plurality of valves hingedly mounted in said casing to control said passage with their axes approximately parallel to each other and at opposite sides of an axial plane of the bottle neck, a seat for each valve facing toward the mouth of the bottle, there being a vent passage adjacent one of said valves, and an auxiliary flap carried by said valve to close and open said vent passage as said valve closes and opens.
